This invention relates to shipping containers and more particularly to shipping containers of the all metal type and to means to seal or to close up the ends thereof.

One of the objects of the present invention is to provide a simple, efiicient end closure means for an all metal container.

Another object is to provide an improved means to detachably secure an end closure member to an all metal container.

Other objects and advantages will become apparent as the invention is more fully disclosed.

In accordance with the objects of the present invention, I have devised a simple and eiiicient means to detachably secure an end closure member to an all metal container which is clearly disclosed in the accompanying drawing, wherein- Fig. l is a side elevational view partly in section of an all metal container incorporating the present invention;

Fig. 2 is a top plan view of the same;

Fig. 3 is an enlarged sectional view of the elements comprising the end closure means of the present invention.

Fig. 4 is a sectional View along plane 4-4, Fig. 3 and Fig. 5 is an enlarged perspective view of one of the elements comprising the end closure means.

Referring to the drawing an all metal container l is shown which is comprised of sheet metal rolled to the desired tubular size and shape and seam welded together'. Container l is provided with a bottom 2 welded thereto, and an end closure member 3 having an annular flange 4 adapted to be positioned about the outer periphery of the open end of the container l. Means must be provided to retain the end closure member in position.

I provide this means by welding to the outer face of the container adjacent the open end thereof, a plurality of clip members 5 shaped substantially in the configuration indicated in F ig. 5. Preferably the clip member is welded to the container so that the lower section 6 of the clip is the only portion thereof welded and so that the bent over clip section (identified by numeral 5) will extend inwardly over the container edge. The end closure member 3 can then be readily placed lin position by springing back the clip members. I

Thereafter I drive a nail 7 or similarz` wedge element through the clip member and the end closure member so that the nail passes between the outer face of the container and the inner face of the annular flange 4 as indicated in Figs. 3 and 4. rlhe deforming of the flange and container walls by the nail is only to such an extent as to permit the nail to pass between the contacting surfaces. The nail or similar wedge I,

element is thereby frictionally engaged so that a definite effort to release the saine must be made. The extent of the frictional engagement of parts is dependent upon the nail size, length, smoothness of surfaces and as to how tightly the annular flange engages the container end, as well as other factors.

It is apparent that many modifications and departures may be made in the above speciiic embodiment without departing essentially from the nature and scope of the'* same as may be encompassed within the following claims.

What I claim is:

1. In a container of the all metal type, end closure means comprising an end closure member provided with an annular flange adapted to enclose the container end, a clip member welded at one end to the container and adapted at the other to extend over theV container end to overlap the end closure"- member and a wedge element adapted to be driven through the clip and end closure member and between the contacting faces of the flange and container wall.

2. A container of the all metall type corni prising a welded container assembly and a removable end closure member provided with an annular flange adapted to enclose the container end and means to retain the member in end closing position comprising through the clip and end closure member and between the contacting faces of the flange and container wall.

3. In an all metal container, means to retain an end closure member in end closing 5 position comprising a clip member and a wedge element, said clip member `being adapted to be welded at one end to a container wall and to overlap the container end and end closure member and said wedge element being adapted to be driven through the clip and end closure member and to wedge the end closure member and container end to ther.

witness whereof, I have hereunto signed my name.

RALPH B. PORTER.
